Good question! I don’t know what is covered in IB math HL, as it is a two-year course, and IB math SL is also two-year. We were told that the school didn’t have good passing record in the past for IB SL math, so a few years ago they stopped using IB math and started AP Calculus AB/BC in place of IB math SL. We were also told that IB is revamping their math curriculum. But we would have preferred higher math courses were offered.
